We have a garden that's 100'x50'. The chicken coop is inside it in one corner. The whole thing is fenced with a 11 or 12 foot fence. The fence is made of welded wire with 3"x2" squares. Do I need to worry about critters squeezing through those holes or climbing over to cause the chickens trouble is they are allowed to run free in the garden? Will my birds try to fly up to the top of the wire to roost? Can they? Our biggest predators around here are hawks, owls, fox, coyote, maybe some racoons, and I hear there is a mountain lion that comes through this area. I've seen prints the size of my hand.... I would really love your experienced thoughts on this. I want them to have more room to roam safely. Thanks!!!
